Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS LettersPolyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Polyextremophilic Bacteria from High Altitude Andean Lakes: Arsenic Resistance Profiles and Biofilm Production [PDF]
BioMed Research International, Volume 2019, Issue 1, 2019., 2019 High levels of arsenic present in the High Altitude Andean Lakes (HAALs) ecosystems selected arsenic‐resistant microbial communities which are of novel interest to study adaptations mechanisms potentially useful in bioremediation processes. We herein performed a detailed characterization of the arsenic tolerance profiles and the biofilm production of ...
